Accredited Drug Testing provides comprehensive hair follicle drug assessments in Midfield, Texas. If you require a hair drug or alcohol analysis, Accredited Drug Testing excels in hair testing, with facilities across all cities Nationwide to conduct exams. Typically, 1.5 to 2 inches of hair from the head or body is needed. Hair tests can evaluate for drugs, alcohol/ETG, or other customized purposes.
Recently, the approach to drug testing has increasingly included hair follicle drug testing. Numerous employers, courts, and Substance Abuse specialists mandate a hair drug assessment over standard urine tests. This test is preferred by employers endorsing zero-tolerance policies, judicial systems, and probationary individuals. The chief advantage of the hair follicle drug test is its extended detection window, usually up to 90 days, conducted in a monitored collection process, making it difficult to manipulate. However, for detecting drug usage within the last 5 days, urine tests remain unsurpassed in accuracy.

Hair testing has gained recognition as an effective means for detecting the use of drugs and alcohol. Hair serves as a long-term record of alcohol and drug ingestion by embedding biomarkers within the fibers of the hair as it grows. When collected near the scalp, hair can offer a detection window of up to three months for alcohol and various drugs. Hair is easy to collect, somewhat challenging to tamper with, and simple to transport.
A 1.5-inch segment consisting of approximately 200 strands of hair (roughly the size of a #2 pencil) closest to the scalp yields 100mg of hair, the optimal amount for testing and verification. For EtG, additional tests, and/or analysis beyond 10 panels, 150mg of the sample is advisable. It's recommended to weigh the specimen using a jeweler’s scale. If scalp hair is not obtainable, a comparable quantity of body hair is acceptable. When referring to head hair, it exclusively means scalp hair. Body hair encompasses all other types of hair (facial, axillary, etc.).
Process Overview
The primary steps in the laboratory handling of a drug test are Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the initial processing of a sample within a laboratory's system. This step includes verifying the secure sealing and proper shipping of the sample, assigning a unique LAN (Laboratory Accessioning Number), and completing any supplemental data entry absent in an electronic chain of custody system.
Screening constitutes an initial rapid assessment for substances of abuse. While Screening is a cost-efficient method to dismiss drug usage in most samples, a positive result needs confirmation to be legally valid. Any samples showing a presumptive positive in Screening require a subsequent confirmation step.
Should a sample exhibit a presumptive positive during Screening, additional hair is extracted from the initial sample for the Extraction process. In this stage, drugs are isolated from hair at much lower concentrations than in other methods (e.g., urine or oral fluid), rendering hair drug testing the most challenging methodology.
Confirmation of any positive screening result is completed using GC/MS, GC/MS/MS, or LC/MS/MS. All samples that presumptively test positive are washed before confirmation as necessary. The complete laboratory procedure from Accessioning to Confirmation is assessed under the CAP (College of American Pathologists) Hair designation and the accreditation to ISO / IEC 17025 standards.
Advantages of hair drug testing:
Limitations:
Note: Although often termed as "hair follicle tests", the test itself examines the hair strand rather than the hair follicle beneath the scalp

With its multidisciplinary nature, hair testing brings together researchers, scientists, and experts from various domains to develop innovative techniques, explore new methodologies, and address emerging concerns, responding to the ever-evolving challenges of drug abuse, therapeutic drug monitoring, and environmental exposures to pollutants.
The joint meeting of the Society of Hair Testing (SoHT) and the Italian Group of Forensic Toxicologists (GTFI) was organized in Verona, June 8–10, 2022, and hosted by the Legal Medicine team of the Verona University Hospital, directed by Franco Tagliaro together with Federica Bortolotti and Rossella Gottardo.
It served as a prominent platform for knowledge exchange and collaboration, facilitating groundbreaking advancements in hair testing and analysis. In this special issue of Drug Testing and Analysis, we aim to showcase the remarkable manuscripts presented at this significant event, shedding light on the latest research and highlighting the future directions in this field.
Novel Analytical Techniques: The Verona meeting witnessed the unveiling of cutting-edge analytical techniques, offering enhanced sensitivity, selectivity, and accuracy for drug testing. Remarkable advancements in sample preparation, detection, and identification of drug compounds have been presented. The manuscripts in this section presented novel approaches, such as multianalyte methods and on-line preparation which can enable rapid analysis and improve thorough forensic investigations.
Biomarkers and Pharmacokinetics: The identification and validation of reliable biomarkers and pharmacokinetic studies are fundamental aspects of drug testing and analysis. The impact of hair treatments on the oxidation/decomposition of drugs in hair was also explored, as the long-term fate of drugs incorporated in the keratin matrix. Furthermore, the SoHT meeting in Verona featured research on the identification and quantification of alcohol abuse biomarkers, their stability, and their correlation with exposure and other biomarkers.
Forensic Applications and Interpretation: One of the vital objectives of hair testing is its application in forensic investigations and legal proceedings. The SoHT meeting in Verona emphasized the significance of rigorous interpretation of analytical results and the need for standardized protocols. Manuscripts in this section present advancements in forensic toxicology, and have explored the challenges posed by emerging designer drugs and strategies to combat their proliferation. The pitfalls encountered when the exogenous/endogenous nature of a substance is questioned were presented and discussed. The special issue presents also manuscripts that delve into the ethical implications of drug testing in drug facilitated sexual assaults.
Clinical Applications of hair testing are witnessed by the insight on environmental tobacco smoke exposure, assessed by hair analysis in a population of students and the study of in utero-exposure to drugs of abuse through neonatal hair analysis. Exposure to drugs was also important in cases of child abuse/neglect, when the clinical purpose of hair testing merge with its forensic applications.
The legal framework surrounding hair testing and the achievement of guidelines to ensure fairness, accuracy, and confidentiality in drug testing practices have also been discussed,and the SoHT consensus on general hair testing and testing for drugs of abuse was presented at the meeting and published as a Letter to the Editor.
In conclusion, the special issue of Drug Testing and Analysis, featuring manuscripts from the SoHT–GTFI meeting in Verona 2022, reflects the remarkable advancements achieved in this field. The manuscripts provide valuable insights into novel analytical techniques, biomarkers, pharmacokinetics, forensic applications, and ethical considerations. As we embrace these advancements, we pave the way for a safer, healthier society, where drug testing and analysis serve as powerful tools in protecting public health and maintaining integrity in various sectors. The research presented in this special issue will undoubtedly shape the future of drug testing and analysis, fostering collaboration and inspiring further innovation in this crucial area of scientific inquiry.
